![\boxed {\boxed {\sf 384 \ ft^3}}](https://tex.z-dn.net/?f=%5Cboxed%20%7B%5Cboxed%20%7B%5Csf%20384%20%5C%20ft%5E3%7D%7D)
Step-by-step explanation:
The volume is the space an object occupies. The volume formula for a cylinder is provided and it is:
![V= \pi r^2 h](https://tex.z-dn.net/?f=V%3D%20%5Cpi%20r%5E2%20h)
Where:
The radius is the distance from the center of the circle to the edge, and it is 4 feet. The height is 8 feet. We are told to use 3 for pi.
Substitute the values into the formula.
![V= (3)(4 \ ft)^2 (8 \ ft)](https://tex.z-dn.net/?f=V%3D%20%283%29%284%20%5C%20ft%29%5E2%20%288%20%5C%20ft%29)
Solve the exponent.
- (4 ft)²= 4 ft * 4 ft = 16 ft²
![V= (3)(16 \ ft^2)(8 \ ft)](https://tex.z-dn.net/?f=V%3D%20%283%29%2816%20%5C%20ft%5E2%29%288%20%5C%20ft%29)
Multiply the three numbers together.
![V= 48 \ ft^2 (8 \ ft)](https://tex.z-dn.net/?f=V%3D%2048%20%5C%20ft%5E2%20%288%20%5C%20ft%29)
![V= 384 \ ft^3](https://tex.z-dn.net/?f=V%3D%20384%20%5C%20ft%5E3)
The volume of the cylinder is approximately <u>384 cubic feet.</u>
Answer:
9/10
Step-by-step explanation:
4/10 + 2/10 + 3/10 = 9/10
4 + 2 + 3 = 9
Answer:
slope is undefined
ex. a straight vertical line like x = 2 would have an undefined slope
Step-by-step explanation:
formula is
y2-y1 / x2-x1
-13 + 9 / -5 + 5
-4 / 0
slope is undefined
straight vertical line like x = 2 would have an undefined slope
undefined slope is the slope of any vertical line that goes up or down. There is no horizontal movement and hence the denominator is zero while calculating the slope. Thus the slope of the line is undefined.
